Pattern modifiers are not consistent

[LarsHassler]

Description

Modifiers on the json files within patternlab are separated by ~ (button~primary.json). But the definition in the patternlab-to-gemini.json config has to be done with - (due to the ids within the markup).
This is not consistent.

Expected behavior

I want to use atoms-button~primary as a key in the patterns section of the patternlab-to-gemini config file.
